I'm not sure, if I'd the same problem, but it seems similar: After a while, game "freezes". Sound turns to noise - repeating few ms of last sound played, screen lock for a few seconds. Then continue, but skip forward in game and vehicle is counts as continuing in last action defined by keys pressed in the moment of freezing. This is grade up to almost game is freezed. Then I can see some slideshow of mountains panorama and after another while game crash with "abnormal terminatin" message.
